The author shares their experience creating a command line tool for translating Chinese text to English using Swift. Initially, they sought an API for translation but faced challenges with tokens and rate limits. Instead, they decided to leverage macOS's built-in Translation features. After some initial attempts with Zig, they switched to Swift, which they were looking to learn anyway. They started with a simple command line template that utilized the ArgumentParser library and the Figlet package for formatting. The development process revealed several hurdles. The author encountered issues with the TranslationSession class, which required a known source language and was restricted to macOS 26. They had trouble setting the platform version in the Package.swift file and had to adjust the swift-tools-version comment to resolve that. The main challenge arose when trying to call the async translate function within a synchronous context. After some trial and error, they implemented a DispatchSemaphore to manage the async task, allowing them to wait for the translation to complete before exiting. In summary, the article provides a detailed account of the author's journey through various programming challenges and discoveries while building a translation tool. It highlights the technical obstacles faced, the solutions implemented, and the learning curve associated with transitioning from one programming language to another. The process reflects a hands-on approach to problem-solving and adaptation in software development.
